Handel
Regular
I fought a battle having freshly recruited units vs an enemy which was keeping several high level prisoners. I won the battle and all of my freshly recruited troops were unconsious, so I "uncaptured" them and took the high level prisoners on their slots... and suddenly all the unconsious units become full health "rescued prisoners"... So if I had a place for them I could take them all back and voila - instant healing for them!
